FELT-CUTTING TOOL.

Applicatoin filed December This invention relates to mechanics handtools of the character known as s'hears,snips or cutters, and it has forits principal object such a tool which will cut sheet felt and similarfibrous material, particularly in the cutting out of washers and gasketsas so largely used in automobile work.

With an idea of giving a clear impression of just what the toolaccomplishes so that its following detailed description will be easilyunderstood, it should be noted that in order to cut a washer from a verythick piece of felt, a pair of scissors cannot be used for if the feltis hard, they will not cut at all, and there is no way by which they canbe brought into action'for cutting out the hole in the washer especiallyif the hole is but an inch or two in diameter.

There are revolving cutters which will do the work on large felt washersbut they are expensive, not readily portable, as they require to be usedon a bench, andarenotat all adapted to the cutting of other forms thanround.

Consequently the mechanic always must resort to the use of a hard woodblock with a chisel and hammer, or a sharp knife to ardously cut out thedesired forms.

However, with the simple tool shown in the accompanying drawings,awasher of any size, or any other shape, may be quickly and easily cutfrom the toughest felt, leather, rubber or other sheet material and byanyone with practically no experience.

In the drawings 1- Figure 1 is a perspective view of the complete tooldrawn substantially full size with the lever as though depressed by anopera-- tor and the blade forced downward through the anvil.

Figures 2 and 3 are detached front and side views of the plunger knife,and

Figure a is an enlarged front sectional view of the blade and anvilshowing a modified sharpening of the cutting edge of the blade.

The device as shown in the drawings takes the form of a plier or punchlike hand tool having a body 1 with a U-shaped handle 2 through anopening formed in the body and abnormally hard cut.

is positioned with'its blade directed toward the anvil so as to snuglyenter a slot 7 therein when the plunger is moved in a direction towardthe anvil. I To operate the plunger, a lever handle 8 15 provided whichpasses through a slot in the end of the plunger being pivoted to it at 9andextending forward of the plunger and pivoted at 10 to a link 11 inturn pivoted atv 12 to a horn 13 extending forwardly from the body. a iSurrounding the plunger is a spiral compression spring 14- reactingbetween the top of the body 1 and a pin 15 projecting from the plungerand which spring serves to n'ormally hold the plunger and lever raisedto the position indicated by the dotted lines so that the point only ofthe blade will project from the body. I The space between'the upper andlower portions of the U handle is'large enough to receive the fingers ofthe operators hand and in addition the thickest sheet of material whichit is desired to cut, so that a large cutting on smaller pieces ofmaterial, the

lingers of the operating hand may grip the under run of the -U handlewith the thumb portion of the hand placed over the lever 8 for forcingthe blade through the material into the anvil and thereby serve also tosteady the anvil against deflection due to an The slot 7 in the anvilispreferably somewhat longer than the width of the blade, a snug lit forthe thickness of the blade and the cutting edge of the blade is formedat an I outwardly slanting angle to receive the material'and with apoint at its inner edge.

The cutting edge in relation to the anvil edges may vary somewhat withdifferent usage, and Figures 2 and 3 show a single shear blade whichwould have a cutting ac- 1G0 tion against one side of the anvil slot,whereas Figure .irSllOYS a square edge blade 5 having a shearing actionagainst both edges of the anvil. i V a The rearwardly slanting bladewith point as shown in Figure 1 at 5' is of great importance for thepoint is used to locate the beginning of the out and the material is fedwith the left hand into the tool against the slanted edge while'theplunger is operated like a punch by the right hand gripping the handle 2and lever 8 as described.

Thus, a out can be started at any point within a sheet of material, suchas for instance, the cutting out of a hole in a felt Washer, and withthe greatest facility the cut may be given any required curve by guidingthe material in the desired direction against th blade while working thereciprocating blade up and down through it, in fact with the leverage ofthe tool shown, felt a quarter 01"? an inch or more in thicl-: ness canbe handled about as easily as paper with an ordinary pair of scissors.

The lever 8 extending through the s"-""ted portion of the plunger prev.its same from turning out of alignment with the slot in the anviland isa simple way of overcoming any necessity of splining the plunger tothebody, the this may also be resorted to if desired.
